I have been doing this for over a year now. I can report the following additional change. At age 60 I feel the best I have felt in well over a decade. At Austin Personal Training and at New Orleans Fitness Trainerswe can help you gradually build up to a high intensity strength training or an aerobic high intensity training program that is safe, effective, and efficient for your age and condition. You need not spend hours in the gym to feel better, look better, and perform better.
